Pietro Musumeci11/10/22, 8:30 AMWG7 Oral: Radiation Generation and Advanced ConceptsContributed Oral
In this paper we discuss the design of polarized positron source for an e+e- linear collider based on polarization transfer from circularly polarized gamma-ray photons in a conversion target. A very high flux of gamma-ray photons can be obtained via inverse compton scattering a high current ultra-relativistic electron beam with an intense laser pulse circulating in an optical cavity. In order...

Development of compact, Laser Plasma Acceleration (LPA)-based sources for positrons is a key step in the R&D effort towards development of a TeV collider. The conventional production and collection schemes of positron beams cannot be easily transferred to an LPA setup. This is mainly due to the large distance required to transport particles from the production to the acceleration point and the...

164. High intensity laser driven sources of gammas and positrons using BELLA PW Laser Dual BeamlinesStepan Bulanov (LBNL)11/10/22, 9:10 AMWG7 Oral: Radiation Generation and Advanced ConceptsContributed Oral
Recent commissioning of the second laser pulse transport line at the BELLA PW facility enables strong-field quantum electrodynamics (SF-QED) experiments where an intense laser pulse collides with a GeV-class laser-wakefield-accelerated electron beam. An overview of the upgraded BELLA PW facility with a SF-QED experimental layout is presented. According to the simulation results these...

Carl Schroeder (LBNL)11/10/22, 10:30 AMWG7 Oral: Radiation Generation and Advanced ConceptsContributed Oral
Plasma-based accelerators enable compact acceleration of beams to high energy and are considered a potential technology for future linear colliders. Conventional linear colliders require damping rings to generate the required beam emittance for high-energy physics applications. We propose and discuss a plasma-based linear radiation damping system that allows cooling of ultrashort bunches...

Austin Dick (Northern Illinois University)11/10/22, 10:50 AMWG7 Oral: Radiation Generation and Advanced ConceptsContributed Oral
Stochastic Cooling is a feedback system for cooling particle beams in storage rings which uses radiation produced by the beam to correct the average deviation of temporal slices with a duration inversely proportional to the bandwidth. Optical Stochastic Cooling (OSC) uses optical wavelengths which decreases the duration of each slice and, therefore, reduces the incoherent noise each individual...

Maxwell LaBerge11/10/22, 11:10 AMWG5 Oral: Beam Sources, Monitoring, and ControlContributed Oral
Recent breakthroughs in laser wakefield accelerator (LWFA) technology have allowed them to drive free-electron lasers (FELs) [1]. This is made more impressive by the relative lack of phase-space control in plasma accelerators when compared to conventional linear accelerators. However, the complicated phase spaces and microstructures in LWFA beams could be harnessed to accelerate the...

Mr Jeroen Van Tilborg (Lawrence Berkeley National Laboratory)11/10/22, 11:30 AMWG5 Oral: Beam Sources, Monitoring, and ControlContributed Oral
Laser plasma accelerators (LPAs) are capable of producing electron bunches as short as a few femtoseconds at percent-level energy spread. However, measuring the bunch length is not straightforward, let alone unraveling source correlations between the longitudinal position and momentum distribution. Here we present the theoretical framework and preliminary experimental demonstration of a...
